Rising
The 75mm F1.0 Infrared Aiming Lens is a long-wave infrared (LWIR, 8–12μm) lens tailored for 640×480 / 17µm thermal detectors. With its large F1.0 aperture, it delivers outstanding image brightness and detection range, ensuring superior performance in low-contrast and challenging environments.
Engineered for demanding professional applications, this lens provides stable thermal transmission, high resolution, and rugged reliability—making it an excellent choice for defense optics, surveillance systems, UAV payloads, and industrial thermal imagers.
Optimized for 640×480 / 17µm detectors – delivers clear and detailed thermal imagery
Large F1.0 aperture – maximizes thermal sensitivity and extends detection distance
LWIR 8–12μm spectral range – strong adaptability in complete darkness, fog, or smoke
Application-ready – compatible with thermal sights, scopes, and imaging devices
